Slang is a popular, less official and often very current form of language. It is an important part of a living language and is constantly changing as language changes. Slang is often playful, direct and sometimes less respectful than the more official and traditional version of language. So now I'm going to lay it on you! To “lay it on” is American slang for “to tell” or “to explain.”

Slang can take many forms. For example, slang can be local to one city or area. In Washington, D.C. there is a whole set of slang to describe politics and business in the city. For example, the term POTUS stands for President of the United States. POTUS can often be found with his wife, FLOTUS, the first lady of the United States. “Inside the Beltway” is a popular expression that describes the area of Washington, D.C. The beltway is the large highway that circles the city.

The Internet has helped create a whole new kind of computer-related slang. An “angry fruit salad” is an expression that describes a Web site with too many bright colors. “Netiquette” is slang for correct behavior when using the Internet.

Young people often develop the latest slang. For example, to say Special English “rocks” or is “phat” means Special English is really great. A “kegger” is a party where beer is served.  If something is “wack” it is wild and crazy.

Different professions often have their own slang as well. For example, medical workers might refer to a complaining patient as a “gomer”.  A "tough stick" is someone whose veins are difficult to find when he or she needs to have blood taken.

No matter how well you speak English, there are always new and interesting slang words to discover. There are entire dictionaries for describing slang. Many experts do not even agree on what is and what is not slang. Often slang words later become a part of officially accepted language. Official or not, slang is an energetic and exciting part of the American language that continues to change.

Sorry to say,our brains naturally start slowing down at the Cruelty young age of 30.It used to be thought that this couldn’t be helped,but new studies show that people of any age can train their brains to work faster.“Your brain is a learning machine,”saying University of California scientist Dr. Michael Merzenich.Given the right tools,we can train our brains to act like they did when we were younger.All that’s required is the practice designed just for the purpose:a few exercises for the mind.

Merzenich has developed a computer-based training method to speed up the process(过程) in which the brain deals with information (positscience.com).Since much of the data we receive comes through speech,the Brain Fitness Program works with language and hearing to better speed and accuracy(准确性).

Over the course of training,the program starts asking you to distinguish(辨别) sounds (between“dog”and“bog”,for example) at an increasingly faster speed.It’s a bit like tennis instructor,says Merzenich,hitting balls at you—faster and faster to keep you challenged(受到挑战).You may start out slow,but before long you’re pretty quick.

The biggest finding in brain research in the last ten years is that the brain at any age is highly plastic.If you ask your brain to learn,it will learn.And it may even speed up while in the process.

To keep your brain young and plastic you can do one of a million new activities that challenge and excite you:playing table tennis or bridge,doing crossword puzzles,learning a language...“When it comes to preventing ageing,you really do ‘use it or lose it’,”says Barbara Sahakian,professor at Cambridge University.

A.speech training

B.computer languages

A.used                                                            B.mastered

C.developed                                                     D.researched

What can we learn from the text?

A.Practice makes a quick mind.

B.Brain research started ten years ago.

C.Dr. Merzenich is a scientist in computer.

D.People believed nothing could stop the brain slowing down.

Which of the following agrees with the writer’s idea?

A.The training methods work better for the old.

B.People should use the brain to stop it from ageing.

C.The training of the brain should start at an early age.

Brain Jackson, director of the Child – minding Researching Unit, and his colleagues have done a great deal of work in finding out   3   it means for a child to spend the first years of life in the care of a child – minder.

Local authorities are responsible for the registration and supervision (监管) of minders. The regulations   6   adequate provision (保障) for fire, safety and health. Very few minders can   7   these. Yet, not many districts give financial assistance. “This means,” Brain Jackson says, “that when you have one registered minder tested and proved by the local authorities, you can be sure that you will get a dozen unregistered, illegal minders   8  .”

The researchers found themselves   9   into the role of private investigators when they conduct their   10  . Getting up early to do a “Dawn Watch” following mothers through cold, dark streets and nothing where they left their babies, Jackson says, was a long, slow process.
